SpaceX is preparing to launch its Starship megarocket into Earth orbit for the first time, a milestone test for the most powerful rocket ever built and a key step toward Elon Musk's ambitions of reaching the Moon and Mars. The flight is scheduled for Monday, three years after the vehicle's first test flight.
The mission calls for the rocket's upper stage to fly in orbit around the Earth and deploy 26 next-generation Starlink satellites, according to the company's plans. Success would mark the first time the fully stacked Starship system has reached orbital velocity, a threshold that has eluded the program through earlier suborbital and high-altitude test flights.
Starship is designed as a fully reusable super-heavy-lift launch vehicle, with both its first-stage booster and upper-stage spacecraft intended to return to Earth for repeated use. That reusability is central to SpaceX's strategy of driving down the cost of reaching orbit and enabling the high flight rates needed for ambitious missions beyond low Earth orbit.
The test is a major moment for Musk and for NASA, which has selected Starship as the lander for its Artemis program to return astronauts to the lunar surface. The space agency is relying on the vehicle to carry crews from lunar orbit to the Moon's surface, making the rocket's development progress directly relevant to the timeline of U.S. lunar exploration.
Beyond the Moon, Musk has promoted Starship as the centerpiece of his long-term goal of establishing a human presence on Mars. The vehicle's size and planned reusability are intended to support cargo and crew missions on interplanetary trajectories, though those capabilities remain years away and depend on the rocket first proving it can reliably reach and operate in Earth orbit.
The flight also carries near-term commercial significance. Deploying Starlink satellites from Starship would give SpaceX a new and much larger platform for expanding its broadband constellation, which already provides internet service from low Earth orbit. The next-generation satellites are designed to add capacity to that network.
Monday's attempt follows a development campaign marked by explosive setbacks and incremental progress. Three years after the first test flight, the company is now aiming for a full orbital demonstration, a step that would validate the vehicle's propulsion, staging, and payload deployment systems under operational conditions.
A successful orbital flight would not complete the Starship program, but it would provide the most substantial evidence yet that the rocket can perform the core functions required of it. For NASA, the test offers a gauge of whether the lander it has bet on is maturing on a schedule compatible with Artemis. For Musk, it is a test of whether his most powerful rocket can move from experimental flights to routine orbital operations.
